I guess Mladen is more looking for a callback hook on when this happens.
And he's lucky there. :-)

Since imple detail of how this (Adrian's suggestion) works is completely 
based on MC state machine, which already has a notion of (lifecycle) 
callback.

See MC's ControllerContext --> DependencyInfo --> 
addInstallItem(CallbackItem) or addLifecycleCallback(LifecycleCallbackItem).

Where each deployment unit/bundle/jar is represented with 
(Deployment)ControllerContext, hence you can apply (Lifecycle)CallbackItem.

Perhaps move this discussion to MC user forum,
for more impl details / code samples.
